IMPROVEMENT IN DUMPINGCARS.

Speci :ation forming part of Letters Patent No. 151,156, dated May 19, 1874; application filed January 16,' 1874.

To all whom it may concern:

'Be it known that I, FRANCIS PETELEE, of Minneapolis, in the county of Hennepin and State of Minnesota, have invented a new and Improved Dumping-Gar; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference bein g had to the accompanying drawing forming part of this-specification, in which drawing- Figure l represents a longitudinal section of my invention. Fig. 2 is a transverse section of the same. Fig. 3 is an inverted plan of the box detached.

Similar letters indicate corresponding parts.

This invention consists in the arrangement of flanged brackets on triangular supports which rise from the truck-frame, said flanged brackets servin g as the bearings for gudgeons projecting from the sides of metallic bearers which are secured to the bottom of the box, the body of each bearer being received in one of the flanged brackets in such a manner that the box can be readily turned down on either side, while, by the combined action of the bearers and flanged brackets, said box is prevented from upsetting. The hinged sides of thebox are locked by double spring-hooks, which are secured to the body of the box and catch over projections extending from the hinged sides, so that said sides will close readily, and that they can be released with facility each from the opposite'side of the car.

In the drawing, the letter A designates the truckframe,which is supported by four wheels, B. From this truck-frame rise two or more triangular standards, C, to the tops of which are secured flanged brackets a, which form the bearings for metallic bearers ZJ, fastened to the under surface of the box D,the ianges of said brackets being provided with semicircular cavities for the reception of the gudgeons which project from the bearers, while the bodies of said bearers rest between the iianges of the brackets, and thereby the box D is eft'ectually prevented from getting displaced; and if saidbox is turned down on either side, it is not liable to upset, and its contents can be dumped with safety. The box D is provided on its sides with doors E, which are connected to the body of the box by means of straps c and eyes d, so that they can readily swing open when the box is turned down in either direction. To the outside of each of these doors is secured a bar, e, which projects beyond the bottom edge of its door and forms a stop, preventing said door from swinging inward beyond the desired point. On the bottom of the box are secured two pairs of double springhooks, f, which are closed by springs g. The heads of these hooks project beyond the bottom of the box, and, if the doors E are closed, the stops e drop in between the heads of the hooks, and as the hooks close upon them the doors are securely retained in a closed position. The shanks of the hooks f are connected by springs h, to which are attached rods i, which extend through to the opposite side of the box, and are provided at their ends with rings or handles j. By pulling these bars the hooks f are opened andthe doors are released. Each ofthe doors can thus be conveniently released from the opposite side of the car7 either before or after the box has been turned down for the purpose of dumping its contents. From the bottom of the box extend chains k, one on each side, which are provided at their lower ends with eyes l, that can be made to slip over staples m, secured to the truck-frame. By passing a pin, a, through said sta-ples in front ofthe eyes l, the chains are retained and the box is prevented from turning in either direction. The pins a are fastened to the truckframe by chains o, so that they cannot become displaced.

By these means a dumping-car is obtained which is convenient in its operation, which can be constructed cheap and durable, and which is not liable to get out of order.

The brackets a are formed with reversely projecting anges or arms a', which embrace the sides of the standards C, and are secured thereto by means of one or more bolts passing through the arms and flanges, and are thus enabled to resist the thrust of the body when dumped on either side.

In some instances a rib, b', will be formed longitudinally on the bearing-surface of the bracket, which will ride or fit in a ccrrespond ing groove, c', formed in the surface of the bearers b, so that the same will serve as an auxiliary in resisting a forward or backward thrust of the body.

What I claim as new, and desire to secure by Letters Patent, is

1. The bracket a', formed with the open slot and the projecting arms a', in combination with the bearers b, for connecting the body of a dumping-car with its standards, substantially as described, for the purpose specified.

2. The body of a dumping-car connected with and supported upon the point of union of the uprights composing theV standards C, in combination with the brackets a and bearers b, substantially as described, for the purpose specified.

3. The double spring-hooksf7 stops e, secured to the hinged doors of the box D, and rods i, which serve to open said hooks, al1 combined substantially as set forth.

FRANCIS PETELER.
